Impedance device and system for simulating the effect of a head on the vibration activity of a vibrating element

Abstract

The invention proposes an impedance device and system for simulating the effect of a vibrating head on a vibrating part. The impedance device may include a bulk, an elastic part, and a fixed part. The bulk part is connected to the fixed part via an elastic part. The fixed part is a hollow structure, and the fixed part includes a gap. The elastic part is placed in the gap and connected to the fixed part. The elastic part creates a cavity containing the fixed part. The elastic modulus of the elastic part of the vibration direction, where the vibrating mass part is in the range of 600 N / m to 5000 N / m.
